"AJ was quick to respond, gave me plenty of time to look at the project and had a vast knowledge to speak directly to my concerns. His solution for my basement walls was simple and reasonable. He did not try and sell me on unnecessary items that other companies tried to make be buy. His work crew were excellent. They were hard working, quiet, and very clean. They took care of covering everything up, hauling away all the rubble and even some of the collected junk in our basement. The job was completed in 3 days.

Groundworks is the North America’s leading and fastest-growing foundation repair and water management solutions provider. Groundworks is a vertically integrated company with its own manufacturing operations and a world-class software solution, allowing us to serve our customers more effectively. From the first phone call to the annual maintenance offered, our customers have peace of mind knowing we’re there with one mission – to repair, protect and improve their home.

"JES Foundation Repair (A Groundworks Company) proposed a solution for my basement wall reinforcement, and waterproofing. I accepted, and a date was set. They did not show up and it took 8 phone calls and 24 hours to find out that they weren't confident in their proposal. They increased the scope and added 50% to the cost. Stupidly, I signed again as time was wasting and I didn't want to start over with new vendors. JES completed the work while I was out of town. When I got back, there had been heavy rain and there was more water in my basement then I had ever experienced. I contacted my rep via text (impossible to get through by phone as he always was in "Training" when I called). His response was " That doesn't look good, I'll make some calls". I had to make the calls. JES sent several new employees out and they proposed additional work at ADDITIONAL cost. Unable to get satisfaction from mgmt. Had another foundation company finish the job. Do not use!"

DiGiacomo Construction is family owned and operated. We've been in business in the Philadelphia and surrounding areas for over 20 years. We offer free estimates, veteran and senior citizen discounts and we are full licensed and insured. Quality, reliable workmanship at competitive prices are our top priority.

"Digiacomo construction was very professional in two jobs for us at our home. They demoed an old failing retaining wall and built a new wall to support a new garage. We also hired them to pour a new pad of concrete for the garage and a new pad for our back porch. They adjusted plans quickly and efficiently when an obstacle was encountered (our water line was where the original sonic tube would be) and the plan was updated to build around the line. I would generally not be able to be around to discuss plans so they would discuss work with my wife and we're always respectful to her when going over tasks and updates. We will hire them again in the future to complete work on our garden."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Philadelphia, PA

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
